Abstract
Excretory urography was performed routinely in 504 patients with sarcoma, melanoma, pelvic, head and neck, or other localized tumors over a 5‐year period. There were benign abnormalities in 14.4% of the patients examined, tumor associated abnormalities in 10.7%, and 1.4% false positives. The diagnosis of a benign lesion did not change cancer therapy in any patient. Findings on excretory urography were valuable in the management of patients with pelvic and intra‐abdominal tumors. In these patients ureteral obstruction was always caused by tumor. There was a high rate of false positivity in non‐abdominal tumors. No second primary tumors were found.
